A 3D reactive transport model for simulation of the chemical reaction process of ASR at microscale

A 3D reactive transport model at microscale is proposed for simulating the chemical reaction process of alkali silica reaction (ASR) thermodynamically and kinetically including the dissolution of reactive silica, the nucleation and growth of ASR products and the dissolution of calcium hydroxide (CH) and calcium silicate hydrate (C-S-H) as a buffer of Ca2+ and OH− to ASR. The implementation methodologies are firstly explained. Sensitivity...
